Digital Electronics and Logic Gates, Integrated Circuits
- In Analog circuits, the waveforms are continuous and a range of values of voltages are possible.
Ex : amplifier, oscillator circuits. - In digital circuits, the wave forms are pulsated and only discrete values of voltages are possible.
Ex : logic gates. - In the binary system, there are only two digits 0 & 1.
